Buying a new refrigerator is always a joyful event, marking the renewal of household appliances in the kitchen. However, immediately after delivering the unit to the apartment, many make the mistake of hastily plugging in the retail cord. This can lead to serious damage to the compressor, since transportation often occurs in a lying position, causing displacement of technical fluids.
The correct sequence of actions during the first start-up will extend the life of expensive equipment and ensure the safety of products. In this article, we will look in detail at why adaptation time is needed, how to prepare the device for operation, and what nuances you should pay special attention to.
Following simple operating rules in the first hours of operation will allow you to avoid typical problems, such as increased noise, insufficient cooling or failure of the refrigerant circulation system. Let's look at each stage of preparation in detail.
Why you can’t turn on the refrigerator immediately after delivery
The main reason for the ban on instant start lies in the design of the compressor. Inside this unit there is compressor oilwhich, when transported in a horizontal position, can flow into the cooling circuit. If you start the unit immediately, the compressor will begin to run dry, which will lead to rapid wear or jamming.
In addition, during transportation, the equipment is subject to shaking and vibration. Mechanical components should “calm down” and electrical contacts should return to normal after temperature changes, especially if delivery was carried out in winter. A sudden switching on of cold appliances can cause condensation on the control board, which can lead to a short circuit.
⚠️ Attention: If the refrigerator was transported lying down, the settling time should be increased to at least 4-6 hours, and it is better to leave it overnight.
It is also important to consider that modern models with inverter motors Liebherr or Bosch equipped with sophisticated electronics that are sensitive to voltage surges. Before connecting, make sure that the wiring in the house is in good working order and the outlet is grounded.
How long does it take to defend the equipment
The time required to stabilize internal processes directly depends on transportation conditions and ambient temperature. There is no single standard for all models, but there are general recommendations from manufacturers that should be followed to guarantee the safety of the oil. refrigerant and oils.
If the unit was transported in an upright position and was not subjected to strong shaking, it is enough to let it stand for 2-3 hours. This time is needed for the pressure in the system to equalize and possible condensation to evaporate. In the case of horizontal transportation, the process takes longer.
Winter delivery requires special care. When a refrigerator is brought from a cold place into a warm room, moisture forms on the internal parts. It is necessary to wait at least 4-5 hours for the equipment to completely warm up to room temperature before turning it on for the first time.
- ❄️ Summer transportation: 2-3 hours of waiting in a vertical position is sufficient.
- 🚚 Transportation lying down: 4 to 8 hours of rest are required for the oil to drain.
- 🌨️ Winter period: minimum 4-5 hours for acclimatization and drying of condensation.
Do not rush things. It’s better to spend extra hours waiting than to have to deal with expensive compressor repairs later. Remember that Electrolux and Samsung in their manuals indicate that violation of transportation rules may cause refusal of warranty service.
What will happen if you turn it on ahead of time?
If you start the compressor before the oil drains, it can create a plug in the capillary tube. This will lead to the fact that the refrigerator will stop freezing, and the engine will work with overload, which often ends in its combustion.
Preparing for the first start: step-by-step algorithm
Before pressing the power button, you need to perform a number of preparatory steps. They concern not only the device itself, but also the location of its installation. Proper preparation will ensure efficient operation of the system No Frost or static cooling.
First remove all packaging: cardboard, foam, protective film and tape. Pay special attention to the inner containers - remove all stickers from shelves and drawers. Then wash the internal surfaces with warm water and a mild detergent to get rid of the smell of new plastic.
☑️ Checklist before turning on
After cleaning, let the cameras dry completely. Place the shelves and drawers in their places according to the instructions. Make sure that the gap between the back of the refrigerator and the wall is at least 5–7 cm for normal air circulation around the condenser.
| Preparation stage | Action | Importance |
|---|---|---|
| Removing packaging | Remove film, tape, foam | High |
| Hygiene | Rinse the chambers with water and soda | Medium |
| Alignment | Level adjustment | High |
| Electrical | Connecting to a separate outlet | Critical |
It is important to check that the doors close tightly and did not warp. If the equipment is not level, the door may not fully adhere to the seal, which will lead to ice freezing and increased load on the motor.
Setting the temperature mode
After the refrigerator is connected to the network, do not rush to load it with food. First you need to set the temperature. For models with electronic control, this is done through a panel on the door, for mechanical ones - by turning the regulator inside the chamber.
The optimal temperature in the main chamber should be from +2 to +4 degrees Celsius. It is recommended to set the freezer to -18 degrees. Such parameters ensure safe storage of products and efficient operation of the compressor compressor.
⚠️ Attention: Do not immediately set the minimum possible temperature (Super Freeze mode) unless necessary. This will create an excessive load on the system during the first hours of operation.
Let the device run idle for at least 2-3 hours. During this time, it will reach the required temperature, and the automation will turn off the compressor. Only after the first cooling cycle can you start loading products, doing this gradually, in small portions.
If you are the owner of the model Indesit or Atlant with a mechanical regulator, remember that the number on the scale does not mean degrees, but indicates the cooling power. Typically, the average value (3 or 4 out of 7) is optimal for everyday use.
Checking operation and the first hours of operation
The first hours of operation are the break-in period. During this time, the refrigerator may operate continuously, trying to cool the internal volume. This is fine. However, it is worth listening to the sounds that the unit makes. The slight hum of the compressor and the gurgling of refrigerant in the tubes are natural processes.
Check the heating of the side walls. Many modern models, for example Beko or Haier, have a capacitor built into the side walls, so they can heat up noticeably (up to 40–50 degrees). This is not a defect, but a design feature that ensures heat removal.
- 🔊 Sounds: a quiet hum, thermostat clicks, and the sound of flowing liquid are acceptable.
- 🌡️ Temperature: after 3-4 hours it should become noticeably colder inside.
- 💡 Light: the lamp should light up when the door is opened and go out when closed.
If you notice an extraneous knock, body vibration or burning smell, immediately unplug the device. Also an alarming signal is the absence of cold after 5–6 hours of continuous operation. In this case, you need to contact the service center.
Typical errors when turning on for the first time
Even following the instructions, users often make mistakes that nullify all efforts for correct installation. One of the most common is loading warm or hot products into a chamber that has not yet cooled down. This forces the compressor to work at its limit, trying to compensate for the sudden influx of heat.
Another mistake is installing the refrigerator close to the wall or in a niche without gaps. Violation of heat exchange leads to overheating of the motor and increased energy consumption. It is also not recommended to place the refrigerator next to the stove or radiators.
⚠️ Attention: Never use extension cords or tees to connect the refrigerator. Direct connection to a separate, working outlet with grounding is the only safe option.
Some users neglect to check the level. If the refrigerator is tilted, the oil in the compressor may be unevenly distributed and the door may not close tightly. Use a building level or simply pour some water into a glass and place it on a shelf to check the horizon.
Remember that careful operation from the first minutes extends the life of the equipment. Models LG and Whirlpool are known for their reliability, but only if the installation and startup rules described in the user manual are followed.
Is it possible to turn on the refrigerator immediately if it was only transported in an elevator?
Yes, if transportation in the elevator was carried out strictly in a vertical position without strong shaking and tilts of more than 40 degrees, it is enough to let the equipment stand for 1-2 hours to stabilize the temperature and pressure before turning it on.
Why does the refrigerator hum loudly after the first turn on?
In the first hours of operation, the compressor may work more intensely than usual, trying to cool the warm volume of the chamber. Also, the new compressor may sound louder than usual due to worn-in parts. If the noise does not subside after a day or is accompanied by vibration, call a technician.
Do you need to wash the inside of the refrigerator before first use?
Required. During production and storage in warehouses, dust, technical grease or packaging odors may remain inside. Wipe all surfaces with a damp cloth with a mild detergent and let dry before turning on.
What to do if the refrigerator does not freeze after 5 hours of operation?
Check whether the door closes tightly, whether the chamber is overloaded with food, and whether the temperature is set correctly. If the equipment has been idling for more than 6 hours and it is not cold inside, there may be a freon leak or a compressor failure during transportation - contact the service.
